IMPROVEMENT IN TOGGLE-JOINTS FOR SAW-FRAMES.

Specication forming part of Letters Patent No. 123,998, dated February 27, 1872; antedated February 1'7, 1872.

I, GEO. R. KEuBALL, of Middletown, in the county of Orange and State of New York, have invented an Improvement in the Construction of a Toggle-Joint to be applied to toggle-bars in buck-saw frames or for other purposes, of which the following is a specification:

My invention consists of p plates having a raised part or thickness on one end, which hook into a rin g 5 said plates are riveted or otherwise made fast to toggle-bars, so as to form a toggle-joint, the projecting part, which hooks in the ring, being tt-ed and forming a segment of a circle to work .on the inside of the ring, and the ends meet and work together, a round end in a socket, and they are confined together by the ring.

In the accompanying drawing, Figure 1 repn resents the joint, as applied in a buck-saw frame, constructed the saine as described in Letters Patent granted to me August 2, 1870. Fig. 2 is a full-size section in the dotted line :v .r of Fig. l. Fig. 3 is a vertical section in the dotted line o o, Fig. 2, the same letters having reference to like parts in all the figures.

A is the ring, with screw B attached. O (l and D D are plates made to project and hook in the ring A, as at mand b b. A larger portion of a circle is formed on the inner end of C C, as at c, and fits in the hollow end of D D, and forms the joint, and the projections form segments of a circle and work in the inside of the ring A, which contines them together, and

the whole constituting a firm toggle-joint. The
